  2. Did anyone try rearing them in myceliated subs? I know Pleurotus sp (oyster mushrooms and related species) generally work fine for many Dorcus larvae and a few of the larger Prosopocoilus species' (eg confucius & giraffa) and Trametes sp. (turkeytail mushrooms and related species) and Ganoderma sp. mycelium work okay for Mesotopus and Allotopus larvae. Most people know of mycelium as being good for rearing larger beetles, but in my experience most larvae grown under the right temperature conditions for the larvae AND the mycelium tend to grow faster than those raised under normal semi-fermented substrates used for rearing Lucanidae larvae under similar temperature environments. Perhaps there's a good matching mycelium species for L. elaphus?

  4. In general, not particular to L. elaphus, if you keep them in just little warmer, that would speed up the growth rate and let them emerge sooner. Feeding them more nutritious substrate can also raise the development much more. But going against the regular time frame is not very normal, of course, and may cause problem later. Those beetles emerged in shorter amount of time than regular time frame (here, I meant more than just couple months of differences) tend to die earlier than normal ones. Not all, but some... Also, the Lucanus rearing guide that @Garin has linked for you is the very general rearing guide for Lucanus spp that requires low-temperature rearing, such as for Lucanus maculifemoratus, L. dybowskyi, etc. None of US species, as far as I know, requires low-temperature rearing. Not even L. mazama, which occurs in higher elevation in Arizona. If you keep them in ranges of 75-80˚F for those L. maculifemoratus or L. dybowskyi group, the larvae CANNOT survive and just die out of hyperthermia, which is quite different from US species.
  5. I have heard that during the winter, if you can keep them at temps closer to around 60, they seem to do better. I have only bred L elaphus a few years and have never tried it but this year I put the larvae in the garage which gets pretty cold at night during the winter. They seem to be doing well but it's too early to tell, so I won't know until later. Here is a link to a experienced breeder who was talking about this, as well diapause in the frig which I have never tried either. http://insectnet.proboards.com/thread/3047/method-breeding-lucanus-species#ixzz4QOuvpQWv

  7. I am curious as to whether or not there are any things I can do extra to speed up the growth rate of my Lucanus Elaphus. Right now they’re kept at 70-72 degrees, are eating decently woody flake soil, soil is moist and humid but not wet and muddy at all. Just curious is there is anything else to do for pure speed of development. I’m not as concerned about as big as possible - but of course do not want anything unhealthy. In addition, what were your time frame experiences? I’ve read some people have them go from eggs to adult in 1 year and I’ve heard of others have L3 larvae for 2 years. Thanks!

    I'm a complete newb, but I'm excited to learn!

    Welcome to the forum, hope you enjoy it here! 😁

    It may have been part of that same import

    Welcome to the boards! Always great to have some more beetlers around. 🙂
  11. Hullo all! I'm 35, and live in Eastern Wahington, US for the moment (Intend on moving to the coast at some point this year!) I've watched a ridiculous quantity of youtube videos about different beetles and raising/breeding them, which brought me to the Bugs in Cyberspace channel and site, and eventually to here! So far my budget is such that I haven't had the opportunity to purchase any beetles for myself, but I'm cramming as much knowledge in my brain as I can while I save up for some shiny new beetle friends. My favorite US beetles are any of the Crysina, as well as the Phanaeus Vindex. IF you can't tell my favorite color is green I'm excited to join this great group, and to read all I can to learn about all things beetle!
  12. Update: After about 8 months, the majority of these Phellopsis (perhaps all?) appear to be healthy. I began this project with 8 adults collected in May-June 2019. They continue to feed/burrow on multiple species of shelf fungus. The softer ones have been gnawed to dust. I keep them on a vertical humidity gradient — I keep the thin bottom layer of leaves/wood/moss slightly damp, and let the pile of brackets above become more dry. They move around the enclosure a lot, mostly at night. They’re incredibly shy, I’ve basically never directly observed them eating or walking because simply the act of removing the lid causes them to tuck and freeze for extended periods of time. I've seen no mating, egg laying, or larvae. Larvae are likely to be in the bracket interiors. I’ve broken open a couple pieces but so far haven’t seen any definitive larval tunnels. Obviously I don't want to rough them up too much, so I'm trying to be patient. Photos below: - Adult just hanging out on a dry piece of moss - Powdery remains of one if the older/softer brackets - Individual wedged into a crack on a harder bracket - The approximately 12-inch wide enclosure - Individual burrowed more deeply, head first, into a bracket

    Alobates pensylvanica care?

    Hi - I thought I’d update about this fun Allobates project. At 7+ months, most of the beetles I collected remain alive and active, mostly at night. They cluster together under wood pieces or burrowed into wood during the day. i keep the enclosure humid (damp substrate, low ventilation) but not soaked. I keep them supplied with very old well-decomposed wood (soft, white, and easily broken apart by hand). Wood remains Slightly damp on the outside due to the humid enclosure, but internally it’s mostly dry. adults constantly chew the wood. As Noted above, I don’t know whether they’re eating it. When I set out grain based foods they are gone in the morning. However the enclosure contains stray isopods that may be eating it. breaking apart the wood shows larvae living inside. I find only one larva per chunk, so I suspect cannibalism. I’m trying to alleviate this by adding lots more wood. Pictures below show an adult wandering at night, a small larva, and a large larva.

    Osmoderma advice?

    Hello - here's an update on this fun and interesting project. The L2-ish larvae I originally collected in May 2018 emerged as adults in March 2019 (about 10 months). Of the original 20 larvae, I estimate 9 or 10 survived to adulthood. This 50% mortality was maybe expected, because i did a lot of handling and messing around with them trying to get their enclosure set up and just poking around to see what was happening with them. I also badly neglected their substrate in the final months. i didn't prepare enough material to replace the substrate before the winter was over. Whatever survived basically did so on frass for the last couple months. The new adults were dead by mid-summer 2019. I let the enclosure sit undisturbed, and finally saw a few grubs through the clear plastic sides in September 2019. Huzzah! Several new adults have now begun to emerge in January 2020 (about 6 - 7 months). This is my first experience collecting a local native beetle species, educating myself about its needs, and successfully running a breeding project. Shout out to the helpful folks here who have helped me along the way with good advice and encouragement. Notes: - Adults spend lots of time out of sight under the substrate surface. I guess they're called "Hermit" beetles for a reason. - My adults prefer apple. I've tried pear, banana, and peach. Apple is what gets most of their attention. - My adults don't seem to feed frequently – certainly not as frequently as Gymnetis thula, which spend hours-long stretches on fruit. Perhaps Osmoderma are more active at night when i miss them? - As I was warned, pupal cells have thin, fragile walls. A few times (mostly during substrate changes) I've broken the cells and the larvae eventually eclosed while exposed on the surface. Often there were no ill effects, but a couple of these exposed eclosures resulted in mis-shapen elytra.

    Did these all come in on a museum import? I know the major supplier usually does two imports a year, and the museum I volunteer at just received their beetle shipment. We also got a Hercules beetle.

    Favorite animal and why?

    Strictly talking about vertebrates, there's so many options to choose from, but I'd go with the Giant Armadillo (Priodontes maximus) because Armadillos are basically the back-boned version of isopods and this particular one is massive among others. Ravens probably come in at a close second due to their large size, overall spooky vibe, and awesome speaking ability. I adore lots of other odd things as well like species from the orders Accipitriformes, Cingulata, Pilosa, Pholidota, Chiroptera, and Rodentia, along with the genus, Lepus, and just fish in general.

    Not yet, working on some ideas that might have a better shot

    Steve, you try getting Hercs legalized in the states yet?
  24. JKim


    Good works!
  25. Mantisfan101


    Awesome beetles! Hopefully we can get these legalized within the US sometime soon...
  26. Ratmosphere


    Actually saw this on Facebook last night lol. Congrats my friend!
  27. Beetle-Experience


    So, after about 14 years of planning and work, I finally held my own Hercules Beetle! (plus a few of my other all-time-favorite beetles that I had never seen in person before) Now to continue work on my ultimate goal.. a beetle rearing facility..
  28. Good to know. I was getting a little worried something was wrong with how long he was on his back. Thanks again for both of your help.
